🔗 Aluminum Profile - Horizontal Connector (Compatible with 20×20 / 30×30 / 40×40)
—— Precise Fit · Stable Load-bearing · Modular Expansion
Designed for 3D printing enthusiasts and makers, this European standard aluminum profile horizontal connector component is perfectly compatible with mainstream 20×20, 30×30, and 40×40 millimeter standard profiles, enabling seamless joining and horizontal reinforcement of multiple profile sections to easily build complex structures such as stable frames, racks, and display stands!
✅ Adjustable Length｜✅ No Screws Needed｜✅ Quick Installation｜✅ Reliable Strength｜✅ Open Ecosystem
🧩 Core Functionality: Horizontal Connection + Structural Reinforcement
This connector is specifically designed to solve the pain point of "horizontal connection between profiles":
- Achieve flush splicing of multiple profile sections: tightly joining two or more profiles of the same specification in the horizontal direction
- Enhance overall rigidity: effectively preventing lateral displacement and twisting through a snap-in embedded design
- Support free extension: the length of the connector can be adjusted arbitrarily to adapt to different span requirements
- No additional fasteners required: adopts a self-locking snap-fit structure, fixed upon insertion, convenient for assembly and disassembly
💡 Particularly suitable for scenarios requiring high stability but also wanting to reduce the number of screws, such as robot chassis, workbench beams, and shelf supports.
🔧 Specifications & Compatibility
Table
| Model | Compatible Profile Size | Connection Method | Default Length | Recommended Material |
|---|---|---|---|---|
| 20×20 mm | 20×20 | Snap-in embedding | 50 mm | PETG / ABS |
| 30×30 mm | 30×30 | Snap-in embedding | 50 mm | PETG / ABS |
| 40×40 mm | 40×40 | Snap-in embedding | 50 mm | PETG / ABS |
🛠️ Freely Adjust Length —— One Model, Multiple Uses!
All models support flexible length adjustment in Bambu Studio or other slicer software via the "Z-axis independent scaling" feature, achieving true "one model, multiple uses."
How to operate?
- Press the hotkey S or click the [Scale] button in the top toolbar
- Uncheck ☑️ "Uniform Scale"
- In the Z-axis input box, set the desired ratio (for example: 200% = 100mm)
- Click confirm to complete the adjustment
💡 Example: Scale the default 50mm height to 300%, and you will get a 150mm long horizontal connector.
✅ X/Y axes remain unchanged, ensuring the cross-section perfectly matches the actual aluminum profile size and guaranteeing assembly accuracy.
🔍 Design Highlights
✅ Snap-in Embedded Structure
- Internally equipped with elastic flanges and guide grooves, automatically aligning and locking upon insertion
- No screws required, quick installation, suitable for frequent disassembly scenarios
- Supports bidirectional insertion, making it more flexible to use
✅ High-Strength Structural Optimization
- Multi-rib reinforcement design to enhance bending resistance
- Thickened bottom treatment to increase contact area and disperse stress
- Smooth surface to avoid scratching the profile surface
✅ No Supports Required for Printing
- The model has been fully optimized and can be printed flat
- All overhangs use an inwardly recessed design to avoid support residue
- No sanding needed after printing, can be installed and used directly
🖨️ Printing Recommendations
Table
| Parameter | Recommended Value |
|---|---|
| Material | PETG (preferred), ABS, PLA |
| Layer Height | 0.2 mm |
| Number of walls | ≥5 (for enhanced edge strength) |
| Infill Density | 40% ～ 80% (adjust according to load) |
| Support | ❌ Not required |
| Print Orientation | Bottom face down, print upright |
⚠️ Note: If printing with PLA, ensure a dry environment; for PETG printing, it is recommended to turn on the fan and use an enclosed printer.
